The Use of MDEA and Mixtures of Amines for Bulk CO2 …

www.bre.com

The use of MDEA and mixtures of amines for bulk CO2 removal was explored using three case studies. A process simulation program called TSWEET was used to study the effect of the amine used and the major operating parameters on the performance of MDEA solutions for bulk CO2 removal. The results showed that MDEA can be used

L and feed liquid F so that L/F = 0.97. Step 4. Using the values from step 3, calculate a new L/F with the equation Step 5. Use the value of L/F from step 4 to recalculate the flash from step 3 and a new value of L/F from step 4. In most cases, the assumed and calculated values agree within the specified criterion within less than five ...

Plan With the information given, we can use Henry’s law, Equation 13.4, to calculate the solubility, S CO 2. Solve S CO 2 = kP CO 2 = (3.4 10 2 mol/L-atm)(4.0 atm) = 0.14 mol/L = 0.14 M Check The units are correct for solubility, and the answer has two significant figures consistent with both the partial pressure of CO
